D5-brane type I superstring background fields in terms of type IIB ones by canonical method and T-duality approach
We consider type IIB superstring theory with embedded D5-brane and choose boundary
conditions which preserve half of the initial supersymmetry. In the canonical approach that …

Noncommutativity in weakly curved background by canonical methods
L Davidović, B Sazdović - Physical Review D—Particles, Fields, Gravitation …, 2011 - APS
Using the canonical method, we investigate the Dp-brane world-volume noncommutativity in
a weakly curved background. The term “weakly curved” means that, in the leading order, the …

Fermionic duality and momenta noncommutativity
In this article we establish the relationship between fermionic T duality and momenta
noncommutativity. This is an extension of a known relation between bosonic T duality and …

Noncommutativity relations in type IIB theory and their supersymmetry
In the present paper we investigate noncommutativity of D9 and D5-brane world-volumes
embedded in space-time of type IIB superstring theory. Boundary conditions, which preserve …

Non-commutativity parameters depend not only on the effective coordinate but on its T-dual as well
L Davidović, B Sazdović - Journal of High Energy Physics, 2011 - Springer
We extend our investigations of the open string propagation in the weakly curved
background to the case when Kalb-Ramond field, beside the infinitesimal term linear in …

Dirichlet boundary conditions in type IIB superstring theory and fermionic T-duality
A bstract In this article we investigate the relation between consequences of Dirichlet
boundary conditions (momenta noncommutativity and parameters of the effective theory) …

T-dual-coordinate dependence makes the effective Kalb-Ramond field nontrivial
L Davidović, B Sazdović - arxiv preprint arxiv:1105.2809, 2011 - arxiv.org
We show that the fact that the string theory is unoriented does not necessarily force the Kalb-
Ramond field to vanish. We investigated the theory of the open string propagating in the …
